471083ca3d ProcFS: Expose the current kernel keymap as /proc/keymap 
Programs can now ask the kernel which keymap is in use by reading from /proc/keymap

00a0e525e6 Kernel+LibKeyboard: Store the keymap name when setting system keymap 
This way we can query the kernel to see which keymap is currently in use.

8dd0c391e9 Shell: Make "fg" set the TTY PGID before SIGCONT'ing the job 
Otherwise the child will get SIGTTIN/SIGTTOU on next TTY I/O.

d9aecc8e08 Shell: Remove unnecessary ignore() in Shell::custom_event() 
Ignoring an event means that it will bubble to the parent Core::Object.
This is not necessary here.

0d6597df2b AK: Remove Stream::operator bool() 
This was only used in one place, and that caused a bug, so I'm removing
this for now since there are no more uses.

ddab7ab693 Kernel: Store TTY's foreground process as a WeakPtr<Process> 
This ensures that we don't leave a stale PGID assigned to the TTY after
the process exits, which would make PID recycling attacks possible.

b3d1a05261 Refactor: Expose const_cast by removing ByteBuffer::warp(const void*, size_t) 
This function did a const_cast internally which made the call side look
"safe". This method is removed completely and call sites are replaced
with ByteBuffer::wrap(const_cast<void*>(data), size) which makes the
behaviour obvious.

7e6fbef8db Kernel: Partial usage of Userspace<T> for the poll syscall 
This change mostly converts poll to Userspace<T> with the caveat
of the fds member of SC_poll_params. It's current usage is a bit
too gnarly for me to take on right now, this appears to need a lot
more love.

In addition to enlightening the syscall to use Userspace<T>, I've
also re-worked most of the handling to use validate_read_and_copy
instead of just directly de-referencing the user pointer. We also
appeared to be missing a re-evaluation of the fds array after the
thread block is awoken.

If a thread is waiting but getting killed, we need to dequeue
the thread from the WaitQueue so that a potential wake before
finalization doesn't happen.

8dea25d974 UserspaceEmulator: Add support for UNIX signals :^) 
The emulator will now register signal handlers for all possible signals
and act as a translation layer between the kernel and the emulated
process.

To get an accurate simulation of signal handling, we duplicate the same
trampoline mechanism used by the kernel's signal delivery system, and
also use the "sigreturn" syscall to return from a signal handler.

Signal masking is not fully implemented yet, but this is pretty cool!
